There are coal dust, dust, and various particulate matter in the coal mining operation environment, and long-term exposure may have an impact on respiratory health. Dust masks, as one of the personal protective equipment, play an important role in coal mining operations. Fangdun masks are designed for industrial dust prevention needs and can provide respiratory protection support for miners.
Filter level selection
According to the GB2626-2019 standard for respiratory protective equipment, self-priming filter type particulate matter respirators, dust masks are classified into three levels based on filtration efficiency: KN95 and KN100. The KN100 grade has a high filtration efficiency for non oily particles and is suitable for work environments with high dust concentrations. Fangdun masks offer KN100 grade products that can meet the protection needs in coal mining environments.
Sealing and adhesion
The protective effect of masks is closely related to the degree of facial fit. The mask adopts food grade liquid silicone cover, special surface technology, and ergonomic design, with a touch similar to that of human skin, making it more comfortable, skin friendly, and closely fitting. Aerospace grade valve disc, still tightly adheres to the valve seat under anti gravity, with low breathing resistance, smooth and comfortable. The door curtain design effectively prevents the accumulation of hot air, rejects stuffiness, and allows for smoother breathing. It is recommended to adjust the nose clip and headband when wearing to ensure a tight fit between the mask and the face.
Material and wearing comfort
The components on the dust mask are made of 100% ABS plastic, which has the characteristics of chemical corrosion resistance, heat resistance, high elasticity and toughness. It is lighter and more durable, and the cost is also higher. It has been widely used in manufacturing industries such as machinery, automobiles, airplanes, ships, and chemical engineering. Emphasis is placed on breathability and lightweight in structural design to reduce discomfort caused by prolonged wearing. When choosing, you can pay attention to the weight of the mask, breathing resistance, and the comfort of the ear or headband.
Usage recommendations
Select the corresponding filtration level based on the dust concentration in the work environment;
Before wearing, check the integrity of the mask to confirm that there is no damage or deformation;
Regularly replace the filter element or mask body to avoid a decrease in protective performance;
Combined with other protective measures such as ventilation, watering to reduce dust, etc., to jointly reduce the risk of dust exposure.
Masks are available in multiple models, and users can choose suitable products based on their actual working conditions and personal needs. Proper selection and standardized use can help provide respiratory protection support for coal mine operators.
